The mechanical switches signal many different situations that may occur on commercial vehiches: differential block, low gears brake failure, reduced gears, handbrake failure, etc. Mechanical switches work both with 12V and with 24V; available are versions with contacts normally open or contacts normally closed, and black seal connector IP 67/CEI EN 60529. All the mechanical switches work both with 12V and with 24V Black seal connector IP 67/CEI EN 60529. Some versions are suitable for use under pressure conditions Silver plated contacts The superseal connector is protected with a rubber cap to prevent dirt intrusion before mounting Maximum life of 125,000 cycles at 3W Ohmic Load Plunger switches have a standard working temperature between -25°C and +80° C. Extended working temperature allows performance between -40°C and *100°C, but 100% guaranteed functionality resumes in the -25°C and +80° C range.
