Your Trusted Power Resistor Provider Since 1925

Custom Rheostats Manufacturers

(Ohmite's high power rheostats have been in use since 1925. The same robust design with wirewound construction is used today and continues to find new applications. The use of resistance wire and an adjustable arm creates a variable resistor suitable for motor and current controls. Ohmite rheostats are designed for live circuit control. Since the current is flowing during adjustment, Ohmite Rheostats carry a UL rating with 11 standard sizes and multiple shaft designs allowing many variations. Ohmite also offers full custom solutions to accommodate specialty applications.)
