EM1 Type Micro Switches

Microswitches Type 'EM1' bear the safety and quality mark of 'ELMECO'.Inspite of small
casing dimensions, the creepage distance and clearance in air so designed that maximum
safety is insured. Precision in design and manufacture as well as high quality of the material
used, results in long mechanical and electrical life. Switches are tasted for compliance
with the characteristics data to insure quality. The switch with its actuating memeber and
auxiliary device has a wide application in industrial and electronics control.
EXECUTIONS :'ELEMECO' Microswitches are available in three different types of bases as
shown below. The various types of actuators are shown in the reverse page and the basic switch
can be supplied with any of these actuators to suit individual requirements. While ordering please
specify the type of base and actuators required.
