ESM and DSM Single and Double Switch Modules The single switch module ESM and the double switch module DSM are readyto-be-installed units, consisting of: Switch: K12, K12G or PVA1H4; the K12G switch has two snap-points and can only be used in DSM. PVA1H4 only to be used in ESM. PC board Rubber cap Optional cable or connector The rubber cap offers the possibility to use the switch modules, ESM and DSM, under severe ambient conditions where dust, water, oil, solvents can effect or destroy the function of switches. With the rubber cap, the two modules are sealed: IP 60 (dust tight) to IP 65 (dust tight and protected against water jets) according to DIN/IEC 529. This is the reason these single or double modules are used in panels and control grips. ITT Cannon Switch Products offers the single and double switch modules as well as complete panels and Multi-Function Grips equipped with these switch modules.
