For commercial and industrial door openers, C&K offers a wide variety of snap switches for door position detection. The “TM” and “A” series switches can handle from 15 to 30A of current, have high cycle life, and can be supplied with a variety of actuator options. The “ZMA” series is a cost effective option for smaller door operators. For manual door operation or reset functions, the PTS645 is available in surface mount or thru-hole with straight or right angle operation for easy soldering to the control board. C&K’s “BD” series is the ideal DIP switch for door operation settings.
