I bought three spring-return, push-type solenoid. I can't remember them being sticky from the start because I only was using one at a time, but they may have been. Now that I tried to work them together, two are so sticky that they have become unusable (even by themselves).
I would like to know whether this may have happened progressively because of pushing them a bit hard (I hardly used them though), or wrong components or because I hooked the three up at the same time.
Here is a bit of info on my setup:
- Spring-return, push-type solenoid. 14 Ohm, 12-24Vdc coil. Intermittent duty
- RECT DIODE 1AMP/400PIV
- 12VDC 3.33A SWITCHING POWER SUPPLY
- N-CHANNEL MOSFET, 55V 22A .06OHM
- Arduino Duemillenove
