Our selection of float switches are manufactured by Honeywell, available in gravity or paddle operated design. The gravity operated version is available only in 3/4" size, while the paddle float switches can be used in pipes with virtually any diameter, and the switching point can be configured by adjusing the paddle size. The gravity float switches use reed relays, while the paddle switches use a high-capacity, fully-encapsulated NC/NO micro-switch. They are especially suitable for monitoring cooling and heating circuits.
