The Series S2D switchlock combines a proven 7 pin radial pin tumbler mechanism with the cost benefits of a zinc alloy body. This switchlock is suitable for applications where simple key controlled switching is required, with the added advantage of being able to form part of a wider keyed alike system using other conventional 7 pin radial pin tumbler items. The switch has a single pole off/on configuration.

The Series S2D switchlock is available in three types of operation: NO, NO/NC or momentary contact. Solder and 6.35mm (1/4”) spade terminal types are offered. To comply with CE regulations, this switchlock is rated at less than 50 volts for alternating current and less than 75 volts for direct current. The outer body is 32mm in length (excluding the terminals) and chrome plated for high durability. Supplied with a body nut and, for keyed to differ locks, with two keys per lock. The key combination of this switchlock can be supplied compatible with the Sidlock C510 Series.
