This roller rotary adjustable lever arm switch provides momentary actuation with a 1NO 1NC contact pair and a rating of 250 VAC 10 A. It is designed for applications that require a temporary signal to energize or deenergize a circuit, with a dual contact configuration for extra control options. Key features and benefits Electrical rating: 250 VAC, 10 A Suitable for controlling line voltage loads within this current and voltage range Contact configuration: 1 normally open (NO) and 1 normally closed (NC) Enables convenient start/stop signaling and inverted feedback in a single device Actuator action: momentary Provides a temporary connection while the lever is pressed; returns to the rest state when released Lever arm: roller rotary adjustable lever arm Designed for smooth operation and adjustable actuation feel Functional versatility The NO contact completes a circuit on actuation, while the NC contact opens; reversed behavior occurs when the actuator is released Construction notes Material and mounting dimensions are not specified in the provided information For mounting details and terminal configuration, refer to the official data sheet Practical applications Start/stop control for small industrial machines or benchtop equipment Press to energize a load via the NO contact; the NC contact provides an inverse signal for status or interlock Control panel signaling and logic inputs Use the NO and NC outputs to drive PLC inputs or relay coils, enabling simple onpress and offpress signaling Mainspowered reset or test functions The momentary action supports reset, test, or shortduration control of auxiliary circuits within the 250 VAC 10 A limit Notes This description preserves the specified specifications: 250 VAC, 10 A rating; roller rotary adjustable lever arm; 1NO 1NC contact configuration; and momentary actuator action For exact mounting options, terminal layout, and installation guidance, please consult the official product datasheet or supplier documentation
