The High voltage tester for routine testing of Switches & Sockets with a specially designed robust fixture to hold ither 20 Nos. switches one way or two way 20 Nos. and 10 Nos. Sockets at a time. The solution comes as a single trolley with easy-to-set test parameters with safety interlocks designed for user safety with respect to electric shock and mechanical fixturing. An advantage of the system is – it gives a high yield (20 Switches OR Sockets are tested in about one minute) thus yielding user safety at a high value for money
