Editing Clare-Pendar Series S840 (section)

===S84010 H3===
The depicted switches were obtained NOS from Electronic Surplus, with no known part number or manufacturer. Based on the design, these are taken to be S84010 H3. Within this set of switches, two different slider designs were found; the sliders differ in the shape of the parts on side 2; one design features a small peg, which may be used for the latching arm, similar to how it functions in [[Clare-Pendar Series S880]].

A small plug fits into the bottom of the switch; below it are two additional terminals, for the lamp, and it provides two sprung receptacles for lamp terminals. As with many other switches, this allows for incandescent lamps to be removed and replaced without needing to desolder and remove the switch.
