Heavy Duty Reed Switch

A surface mounting reed switch and magnet that operates over a much wider gap than standard switches (40mm). Ideal for garage doors and other problem areas such as loose fitting doors and those that --rattle in the wind. Features 8 terminals: 2 for the reed switch itself, 2 for the spring leaf anti-tamper switch, and 4 more for terminating and looping through wires. A small --arrowhead moulded into the units indicate the correct alignment.
