Yes, feel free to order 40 units of the store item $1 increments and note “install solenoid and solenoid driver” but I recommend you follow the YouTube link on this page and install the solenoid and solenoid driver yourself. It’s very easy to do and takes a few minutes. Of course you still need to purchase the solenoid and solenoid driver! Both available on this page: https://www.modelfkeyboards.com/product/xwhatsit-beam-spring-or-model-f-controller/
