Hello Guys.
I have this 2 brand new Solid State relays
(Salsar, SSR-10DA)
SSR Relay (SSR-10DA) - China Solid state relay,ssr,relays in Relay & Contactor

which I am currently use to close NO contact with 24Vdc input from CNC controller manual buttons (spindle CW and spindle CCW).
The LED is is lid when push on/off...but the contact (Load Voltage: 24-380VAC) doesn't seem to close......

Question is...this type of solid state is no good to close the contact?? Or am I just having bad Solid State?
Alternatively....mechanical relay works just fine....
I thought it works just the same?
