High security lock switch limits access

29 November 2006 Circuit & System Protection

A new product from switch manufacturer Lorlin Electronics is the DSL Mains Lock Switch. Fitted with a high security key switch mechanism, the DSL is intended for safety and security applications or where control by authorised users only, is essential.

The DSL lock switch is a rugged design, simple to mount and RoHS-compliant. The lock is mounted to the panel from the front and the electrical switch snaps onto the back of the mechanism. The high security key is a dimpled design, which operates a 6-pin lock with a 90° movement. The key may be inserted into the lock either way up and withdrawn in both the locked and unlocked switch positions. Over 15 000 key combinations are available with options of all different keys or common 'pass' keys for applications requiring single key control of multiple secure systems by supervisors or service engineers.

This lock switch is rated for currents between 4 to 80 A at 250 V a.c. over an operating life of >10 000 cycles. The switch has an operating temperature range of -25 to 85°C, is flame retardant to UL94 V0 and approved to EN 61058. Connection is made via plated brass solder terminals or using optional PCB terminals. Two switching options are available; 2-pole off/on (normally open) or 2-pole on/off (normally closed). With a 3 mm contact gap the snap-on switch mechanism provides mains safety isolation to 3 kV. The switch contacts are silver cadmium and the lock housing is zinc alloy, bright chrome plated with a parallel-sided lock head.

Typical applications for the Lorlin DSL mains lock switch include, security shutters, alarm and security control panels in airports, prisons, police stations etc, factory equipment, instrumentation and electrical control panels.
