Where are these used on the chair ? They are possibly reed relays operated by a magnet</div>

<p style="margin: 0cm; font-family: "Calibri", sans-serif; font-size: 11pt;">This is completely out of synth stuff but maybe you could help identify this part..</p>
<p style="margin: 0cm; font-family: "Calibri", sans-serif; font-size: 11pt;"> </p>
<p style="margin: 0cm; font-family: "Calibri", sans-serif; font-size: 11pt;">It is from a double electric reclining sofa.</p>
<p style="margin: 0cm; font-family: "Calibri", sans-serif; font-size: 11pt;">It has 2 small controls PCB’s. One on each side holding 7 small limit switches<br>
with 3 of these parts that look like resistors.</p>
<p style="margin: 0cm; font-family: "Calibri", sans-serif; font-size: 11pt;">On the sofa’s left side</p>
<p style="margin: 0cm; font-family: "Calibri", sans-serif; font-size: 11pt;">4 of the switches still work but the 3 others<br>
do not operate their motor anymore.</p>
<p style="margin: 0cm; font-family: "Calibri", sans-serif; font-size: 11pt;">The right side still works.</p>
<p style="margin: 0cm; font-family: "Calibri", sans-serif; font-size: 11pt;">I desoldered the 3 parts which are the same</p>
<p style="margin: 0cm; font-family: "Calibri", sans-serif; font-size: 11pt;">and measured them.</p>
<p style="margin: 0cm; font-family: "Calibri", sans-serif; font-size: 11pt;">2 measured 270pf (burned open resistor ?)</p>
<p style="margin: 0cm; font-family: "Calibri", sans-serif; font-size: 11pt;">And the other measures around 1.0 ohm.</p>
<p style="margin: 0cm; font-family: "Calibri", sans-serif; font-size: 11pt;">They operate 29vdc motors.</p>
<p style="margin: 0cm; font-family: "Calibri", sans-serif; font-size: 11pt;"> </p>
<p style="margin: 0cm; font-family: "Calibri", sans-serif; font-size: 11pt;">What do you think ?</p>
