Dear Experts

This is the first time I am posting thread in this Forum. I am a beginner w.r.t. electronics. I am using one circuit (attached herewith) comprising of
1. Pressure Switches 2 Nos. connected in series (specifications attached)
2. Omron Relay 1 No. (G2R-2-SND DC24)
3. Solenoid Coil (24 V DC) 1 No.
The circuit is working fine. We supply components with this circuit within a panel. We have supplied numerous panel but in some of the panels we are facing a problem of failure of 1st Pressure Switch. As per our observation this problem occurs due to excessive current flown in circuit.
Can somebody help to resolve the above issue. Your assistance in this regard would be highly appreciated.

When you present your circuit, it is best to show what contacts switch where otherwise it does not make any logical sense.

An example is you show a relay with n/o and n/c and nothing connected.
One would expect someting to be connected to one or the other to control the solenoid vai a common(this is not shown either)

Then there are your pressure switches, what switches to where and why do they need pos and neg supply?
Ah-ha...open collector output...you'll need to rethink your arrangement there.
