When to Use Input Button and Submit

Question

I am developing a login system, but I have two alternatives, use the type button or type Submit, which one to use?

<div class="layout_login">
    <label for="sizeEmail" id="positionEmail">Email</label>
    <div class="e_mail">
        </br><input class="sizeEmail" type="email" name="e-mail_login">
    </div>
    <label for"sizeSenha" id="positionSenha">Senha</label>
    <div class="senha">
        </br><input class="sizeSenha" type="password" name="senha_login">
    </div>
    <label>Enviar</label>
    <div>
        <input type="submit" << AQUI
