Multi-mode air compressor pressure power switch
View Patent ↗A multi-mode air compressor pressure switch is disclosed. A first mode of operation of the switch has a first range that includes a first cut-out pressure and a first cut-in pressure. A second mode of operation of the switch has a second range that includes a second cut-out pressure and a second cut-in pressure. The second range is smaller than the first range. The second mode of operation adds compressor output over the first mode of operation to extend operable time of a tool that is connected to a compressor that is controlled by the first mode and the second mode.
1. A switch assembly, comprising:
a diaphragm assembly that is configured to move according to a tank pressure of an air compressor;
a first lever connected to the diaphragm assembly and having a first pivot point and a second pivot point; and
a second lever connected at a first end to the first lever through a torsion spring,
wherein the first pivot point is connected to the diaphragm assembly to enable a first mode of operation having a first range that includes a first cut-out pressure and a first cut-in pressure,
wherein the second pivot point, instead of the first pivot point, is connected to the diaphragm assembly to enable a second mode of operation having a second range that includes a second cut-out pressure and a second cut-in pressure,
wherein the second range is smaller than the first range, and
wherein the first cut-out pressure is the same as the second cut-out pressure.
2. The switch assembly according to claim 1 , wherein the second mode of operation adds compressor output over the first mode of operation to extend operable time of a tool that is connected to the air compressor that is controlled by the first mode and the second mode.
3. The switch assembly according to claim 2 , wherein the second lever has a second end that includes a switch electrode that turns a compressor motor on or off.
