Standard detect switches include the low profile SDS with an actuator length of 2.5 mm and over-travel of over 1.6 mm, the KSU with a 1.5 mm actuator and 1 mm over-travel, and the low power consumption IP54 sealed ATS with a 1.5 mm actuator and 0.4 mm of over-travel. The SDS and KSU both have a low actuation force of under 75 grams. To accommodate higher tolerance stackup, C&K offers snap acting switches such as the ZMA series with a pre-travel of 1.43 mm and over-travel of 1.25 mm, the IP65 sealed ZMS with maximum pre-travel of 4.8 mm and over-travel of 2.57 mm, and the IP67 sealed LCW with a maximum pre-travel of 6.2 mm and over-travel of 1 mm. All switches are UL certified. C&K also carries a line of high performance SIM card sockets such as the CCM03 series for meters which utilize GSM or cellular communication.
