Sanwa Denki Co., Ltd. SVS-1WP Vacuum Switch 100 250V 0.5 2.5A

Sanwa Denki SVS-1WP is a waterproof vacuum switch designed for rugged vacuum sensing and two-point control in industrial equipment. Housed in a durable aluminum die-cast enclosure, it provides IP54-equivalent protection against moisture and splashes, making it suitable for environments where water exposure is a concern. The device uses a multi-stage bellows vacuum detection element and a snap-action switching mechanism to deliver reliable ON-OFF signals with minimal cumulative error. It provides two adjustable vacuum setpoints (ON and OFF) and carries an electrical rating of 100–250 V and 0.5–2.5 A. The SVS-1WP supports fluids such as air, gas, oil, and water in vacuum control applications, and is part of Sanwa Denki’s SVS series, which covers a range of vacuum switches for industrial automation, process control, and equipment monitoring. This model is ideal where moisture resistance and precise vacuum detection are required in demanding environments.
