2 Pin Vertical Slide Switch 1P2T — SS-12D16 Right-Angle PCB Mount

The SS-12D16 is a vertical slide switch 1P2T — a 2-pin-footprint SPDT (Single Pole, Double Throw) switch offering simple ON-ON circuit selection in a compact, right-angle-mount package. The right-angle feet allow the switch body to sit flush against the PCB edge, making it well suited for enclosures where the actuator needs to protrude through a side panel slot rather than the top face — a common requirement in handheld devices, small appliances, and edge-mounted control panels.

This right angle slide switch uses a precision-stamped contact blade and a spring-loaded detent mechanism, giving users a clear tactile click at each of the two switch positions. This prevents the actuator from resting in an intermediate, unreliable contact state — an important reliability factor in high-cycle consumer applications. Internally, the 1P2T SPDT slide switch provides one common contact that can be connected to one of two positions, making it ideal for simple ON-ON or A/B circuit selection.

Compared to Vistar’s standard 3-pin vertical 1P2T switches (SS-12D02, SS-12D18), the SS-12D16 is rated for a higher DC50V and uses a lower-profile right-angle foot, giving engineers an alternative footprint option without changing the underlying 1P2T circuit logic. Manufactured in an ISO 9001:2015 certified facility, this PCB mount slide switch is fully compliant with RoHS 3 and REACH regulations.

Below are the complete specifications for the SS-12D16 slide switch, covering electrical, mechanical, and environmental ratings.

What Is a Vertical Slide Switch 1P2T?

A vertical slide switch 1P2T is a through-hole PCB component that provides Single Pole, Double Throw (SPDT) switching in a vertical actuator orientation. The SS-12D16 is a 2-pin variant with right-angle PCB feet, designed for compact board layouts where the actuator needs to protrude through a side panel. The 1P2T configuration means one common contact can be connected to one of two positions, making it ideal for simple ON-ON or A/B circuit selection.

Vistar’s SS-12D16 features precision-stamped phosphor bronze contacts, high-temperature engineering plastic housing rated UL94 V-0, and a positive detent mechanism for crisp tactile feedback[reference:1]. These switches are particularly valued in space-constrained designs because the right-angle feet allow the switch body to sit flush against the PCB edge, enabling side-access operation while keeping the PCB footprint minimal.

Right Angle Slide Switch — Advantages for PCB Design

A right angle slide switch offers several distinct advantages for PCB designers working on compact electronic devices. The right-angle orientation positions the switch body parallel to the PCB surface, significantly reducing the vertical space required compared to standard vertical switches. This makes it ideal for slim enclosures where the actuator needs to exit through a side panel slot rather than the top cover.

The SS-12D16’s right-angle feet provide stable mechanical mounting on the PCB, with the actuator moving perpendicular to the board plane. This orientation simplifies enclosure design and improves cable management, as the actuator access point is on the side rather than the top of the device. For engineers designing handheld devices, small appliances, and edge-mounted control panels, the right-angle slide switch is often the preferred choice.

1P2T SPDT Slide Switch — Circuit Logic Explained

The 1P2T SPDT slide switch configuration is one of the most common switch types in electronics. SPDT stands for Single Pole, Double Throw — one common terminal (the pole) that can be connected to either of two other terminals (the throws). In the SS-12D16, this provides simple ON-ON or A/B circuit selection. Common applications include audio signal routing, power path selection, mode switching, and control signal toggling.

The switch’s spring-loaded detent mechanism ensures the actuator stays firmly in each position, preventing unreliable mid-travel contact states. This mechanical design, combined with the phosphor bronze contacts and gold or silver plating, ensures consistent electrical performance over the switch’s 10,000-cycle rated life.

SS-12D16 vs SS-12D02/SS-12D18 — Choosing the Right Switch

Vistar offers several 1P2T vertical slide switches, each optimized for different applications. The SS-12D16 features right-angle PCB feet and a higher DC50V rating, making it ideal for compact designs where board space is tight and slightly higher voltage headroom is needed. The standard SS-12D02 and SS-12D18 variants use a 3-pin vertical footprint and are rated for DC30V.

Choose SS-12D16 when:

• Your PCB layout benefits from a right-angle mounting footprint
• You need DC50V voltage rating for signal or control circuits
• You require a 2-pin SPDT switch with side-actuated operation
• You want a compact alternative to standard 3-pin vertical switches

For standard vertical mounting applications, consider the SS-12D02 or SS-12D18 variants.

Applications Across Industries

This PCB mount slide switch is widely used across multiple industries. In small appliances, it provides mode or power-path selection in compact consumer devices. Portable electronics use it for ON-ON audio or signal routing in handheld and wearable products. Toys and consumer gadgets benefit from its simple two-position control where board space is limited. Lighting controls, instrumentation panels, and smart home accessories all rely on the SS-12D16 for reliable circuit selection in space-constrained designs.
