4 Pin SMD Tact Switch 6.2×6.2mm (TS-1158) for Compact PCB Keypads and Control Panels

The TS-1158 is a 6.2×6.2 tactile push button switch for boards where a clear click matters more than long travel. When the actuator is pressed, a metal dome inside the body collapses onto the centre contact and closes the circuit. Release the button and the dome springs back, and the circuit opens again. Travel is 0.2±0.10mm, short enough for thin housings, while the click is distinct enough that the user knows the press registered without looking at the panel.

The body sits in the same size class as the common 6×6 tact switch, so it fits many existing keypad layouts. Always compare the land pattern on the drawing before swapping one part for another. Four SMD terminals hold the switch to the pads more firmly than a two-terminal type, which helps when a button is pressed tens of thousands of times over the life of a product. Vistar is based in Shenzhen and builds its tactile switches under ISO 9001:2015, with every unit tested for operating force and electrical performance.

If you are still deciding on a format, the tactile switch selection guide and the overview of tactile switch types explain the differences between SMT and through-hole mounting, sealing levels and force options. The full range is listed on our tactile switch category page.

The table below gives the rated values for this SMT tactile switch 4 pin model, taken from the Vistar product data.

A 50mA, 12VDC rating means the switch is meant for signal paths, such as a line into a microcontroller input or a keypad matrix. It is not meant to switch motors, relays or other power loads directly. For a deeper look at how force, travel and life ratings interact, read our tactile switch specifications guide.

A 6×6 SMD tactile switch is the usual choice when a panel needs a finger-sized button with a definite click and the board is assembled on an SMT line. This 6.2mm version is used in the following products.

If the product will be used in a bedroom, hospital or office where click noise is a problem, look at the 6x6x5mm silent tactile switches. If the layout needs a grounded shell, the 6*6 tact switch with ground pin is a closer match.

Force and life are the two choices you make when ordering this switch. A rough usage estimate settles them faster than any rule of thumb. A remote control pressed 30 times a day will use up 50,000 cycles in about four and a half years. A wall panel pressed a few times a week will never reach either figure, so the lower life rating is enough there.

For force, 180gf suits thumb-operated devices and small keypads where people press often and a light touch reduces fatigue. 260gf is the better pick where the button can be touched by accident. If your keycap or rubber overlay adds its own spring force, test both values on samples before you commit to a full order.

Other formats are available if this size does not suit the layout. A smaller footprint is covered by the 4×4 SMD tact switch. Side-facing buttons can use the 2 pin horizontal tact switch, and backlit panels can use the 12mm LED tact switch.

As an SMD part, the switch is intended for reflow soldering. The general process is described in this overview of surface-mount technology, and IPC publishes the industry standards for soldering and assembly. Ask us for the recommended reflow profile when you request the drawing.

Standard MOQ is 1,000 pieces. Free samples are available for qualified projects. To request samples of the 4 pin SMD tact switch 6.2×6.2, send your application, expected volume and the force and life options you want to sales@vistarelectronics.com, or use the contact page.

Vistar tactile switches are produced under ISO 9001:2015 and comply with RoHS 3 and REACH. If you want to know what the RoHS directive restricts, the linked summary is a good starting point. The Vistar catalog (PDF) lists the wider switch and connector range. When you write incoming inspection criteria, our tactile switch troubleshooting guide explains how open circuits, double-clicks and force drift are tested and diagnosed.
