We make bespoke gas-gap switches as well as some standard types. The standard units are 2.5” (63.5mm) long and are usually mounted upright, but can operate in any orientation. Bespoke types vary in length depending on the application requirements. To design a bespoke switch, we need to know the customer’s thermal requirements for the OFF-state and an idea of ones for the ON-state (e.g. you need to cool a mass from a high temperature to a lower one on some timescale, or you need to dump so many joules of heat of magnetisation from a salt pill). With this information we can estimate the dimensions, feasibility and price of the switch.
