Tactile Switches

C&K offers a broad range of miniature tactile, ultra-miniature tactile and micro miniature tactile switches for printed circuit board mounting. Available in J bend, gull wing, illuminated, sealed, low-profile, low-noise, SMT and through hole versions, C&K’s tactile switches are designed for the most demanding applications.

Pushbutton Switches

C&K’s extensive range of miniature, subminiature and ultra-miniature pushbuttons for printed circuit board, surface mount and panel mount applications include momentary and latching versions with the widest selection of actuator styles, shapes and colors. Available in SPST, SPDT, DPST and DPDT functions, C&K pushbuttons are also available in illuminated, sealed and low-profile configurations, and with smd, threaded or snap-in mounting options.


C&K keyswitches are designed to support high-performance, environmentally demanding applications.
They are available in a large number of combined versions:

  • SMT or THT solder process compatible
  • IP40 or IP67 sealing level
  • LED illumination option
  • SPST, SPDT, DPST or DPDT electrical functions
  • Normally Open or Normally Closed contacts
  • Double step actuation
  • Momentary or latching “push-on/push-off” versions
  • Tactile or Non-tactile feedback
Snap Switches

C&K’s broad range of snap switches includes mini, small, mid size & large heavy duty, and metal case models. These limit switches have a variety of actuator configurations (pin plunger, lever, and roller lever), electrical ratings from low levels up to 30 Amps, and a broad range of operating forces. Terminal styles include PCB through-hole, quick connect, wire leads, screw, solder, formed PC through-hole, flat and step base. Sealed models are available as is SPST, SPDT, DPST and DPDT functionality. Mounting options include vertical or right angle, PCB and snap-in mounting.

Slide Switches

Featuring ultra-miniature, micro, miniature, standard, industrial and power versions, C&K has slide switches compatible for printed circuit board, surface mount and panel mount applications. Available in SPST, SPDT, SP3T, DPST, DPDT, 3PDT, 4PDT and 4P3T functions, C&K provides slide switches with positive detent, sealing, and shorting or non-shorting contacts options.

Detect Switches

With 19 different series of standard detect switches, C&K offers the largest selection in SMT, through-hole, panel and snap-in/chassis and screw-mount versions. C&K’s detect switches are offered in a variety of sizes and shapes, with various actuator orientations including vertical or horizontal, top or side, or right-angle or left, and come with soft actuation force. These detect switches include low profile, compact, micro- and ultra-miniature designs, with some sealed versions available.

Choose from traditional detect, snap-acting, tactile, magnetic reed, or door interlock styles for your optimum detect switch solution. In general, C&K detect switches operate at low current, occupy less space and offer higher life cycles (100k ~ 1M).

DIP Switches
