SERIES 1050 - ENCLOSED SNAP ACTION SWITCHES
UP TO 10 (1,5) A 250 V~
PRODUCT ADVANTAGES
u
Small snap action switches in size
DIN 41635 design B
u
Maximum functional reliability by ten-
sion spring contact system
u
Precise switching accuracy with long
life endurance
u
Special shape of the PCB terminals for
better automatic soldering
u
The versions with mushroom-head
actuators can be approached from all
sides
u
The standard program includes a
number of different ratings and
terminal versions
u
The optional actuators made of
chrome-nickel-steel are available in dif-
ferent shapes and lengths. These can
easily be retrofitted.
