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 :'ELMECO' 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.
