Single & Double Switch Modules – ESM / DSM
The single switch module ESM and
the double switch module DSM are
ready-to-install units, consisting of:
•
Switches:
K12 (for both ESM or DSM)
K12G (DSM only with two
switching-points)
PVA1H4 (ESM only)
PC board
Rubber cap
Optional cable or connector
ESM

•
The rubber cap offers the possibility
to use both switch modules under
severe ambient conditions where
dust, water, oil, solvents etc. can
effect or destroy the function of
standard switches.
With the rubber cap the two modules
are sealed to IP 65 when mounted.
Typical Applications
•
Tractors
•
Harvesting equipment
•
Industrial controls

Exam ple
ESM = single switch module
DSM = double switch module
K12 = (for ESM and DSM)
K12G = with 2 switching-points (DSM only)
PVA
= PVA1H4 (ESM only)
1 = 1 mm (K12)
1.5 = 1.5 mm (K12G)
2.2 = 2.2 mm (PVA1H4)
5N
= 5 N (K12)
3.5N = 3.5 / 7 N (K12G)
3N
= 3 N (PVA1H4)
