Overview

What it is and who it is for

The Seco-Larm SS-090-2H4 is a high-security tubular key lock switch with maintained shunt ON/OFF action. It is a two-terminal SPST switch keyed to key number 1304, and the key can be removed in both the ON and OFF positions.

The contact is rated 2 A at 12 VDC, and the round terminals accept solder or crimp connections. The housing is chrome-plated zinc alloy on a heat-resistant fiber-bakelite base, and the silver-plated contacts have an anti-sulfurating treatment and silicone coating. Seco-Larm uses a patented see-saw contact design that self-adjusts and a patented pick-proof construction.

Seco-Larm offers the SS-199Q slimline plate and SS-299Q single-gang plate, each with a 3/4 in (19 mm) D hole, for mounting this switch, and the SS-090KN-4 spare key for this key number.

  • Best for: keyed shunt ON/OFF switching on alarm system circuits.
  • System fit: low-voltage inputs that take a maintained SPST contact within 2 A at 12 VDC.
  • Important to know: this switch is keyed to #1304; the matching spare key is SS-090KN-4.
