Questions
- Question
- For which pressure switch applications are gold contacts recommended?
- Answer
- For "dry circuit" applications where little or no current is flowing in the circuit to help burn off contact dirt and oxidation. Switches used with solid state circuits often fall in this category.
- Question
- Does Dwyer offer a fully UL/FM/CSA approved explosion proof pressure switch?
- Answer
- Yes. The 1950 and 1950G Series.
- Question
- Can the standard H2 pressure switch be used with water?
- Answer
- No. The brass or SS housing must be specified for compatibility reasons. The aluminum housing can leak into the switch.
- Question
- I am going to order the d/p switch 1950-5-2-S-AT. Option "-AT" is an aluminum tag. I would like to know the size of the tag.
- Answer
- Aluminum tags may contain 2 lines, approximately 9 characters per line.
- Question
- What is the power consumption of a 24 VDC 1950G Pressure Switch?
- Answer
- The Current Draw for the 1950G 120mA @ 24VDC 30mA @ 120 VAC 15mA @ 240 VAC
