International Approvals

UL, CSA, ENEC, CE listings. Over 75 years of engineering excellence. Industry-leading temperature range: up to 204°C [400°F] and as low as –55°C [–67°F].

Configuration

TopWorks Options

Flow / Reverse Flow

Multiple Action

By special use of two or more (up to 6) micro-switches, indicates combinations such as flow/no-flow, two different flow actuation points, or flow/reverse flow.

Stacked SPDT

DPDT Option

Two SPDT micro-switches stacked to provide DPDT function. Available for applications requiring dual-circuit switching.

No Electrical Contacts

Air Operated

Where electrical contacts are not permitted or where pneumatic operation is preferred. Supply pressure: 3 to 20 psi or 20 to 125 psi.

For Turbulent Flows

Dash-Pot Option

Delays switch action up to 30 seconds to avoid false actuation due to cavitation or turbulent flow conditions.

Hermetically Sealed Switches

Designed for applications where maximum electrical rating and maximum sealing are essential. Sealed per MIL-S-8805, design symbol 5 (–67° to +180°F or –55° to 82°C). Military standard construction with listings on the MIL-S-8805 qualified products list.
